A novel approach for encoding and decoding of high storage capacity color QR code

With the enhancement in mobile technology, QR (Quick Response) codes became popular. QR codes are widely used in our daily life from social media websites to cashless shopping wallets, ERP(Enterprise Resource Planning) software implementation to display advertising and digital marketing etc. In this paper we have focused upon one major issue with the QR codes. We have focused upon data various techniques used to increase data storage capacity of QR code. This paper is divided into five subparts. In first part we have introduced about basics of QR codes, their versions, creating and scanning process and its various applications. Then in second part we have written about various features of QR codes, due to them QR code became so popular and we have also discussed about its structure to understand its basic functionality. Thereafter we have compared three different kinds of co des-b ar code, quick response code and color quick response code, on the basis of its storage capacity, error resistance, 360° reading and other factors. Then in fourth part we have reviewed the literature and mentioned various techniques used by researcher to in crease data storage capacity of QR codes. In fifth part of this research paper we have proposed encoding and decoding algorithm, which will result into high storage color QR code. And a t the end, we have discussed about our future directions in order to increase storage capacity of QR codes and make stored information more secure and reliable for the end users.
